摘要：
We present results including a lead electromagnetic model (LEM), power deposition, and RF-induced heating for a set of single electrode leads with straight and helical wires, as regular unshielded lead, and leads with a metallic shield. Our results were obtained numerically, employing 3D electromagnetic and thermal co-simulations at 128 MHz. We observe that the metallic shield raises the LEM calibration factor and thereby it increases the RF-induced heating of the lead with helical wires, a circumstance that previously had mostly been neglected.
